Explosion-proof lamps refer to lamps that take various specific measures to prevent the ignition of surrounding explosive mixtures such as explosive gas environments, explosive dust environments, and gas gases. One of the very important explosion-proof principles of explosion-proof lamps is to limit the temperature of the surface of the casing, the surface of parts or the surface of electronic components in contact with explosive gases and explosive dust, and to limit the temperature of the electrical contact surface to be lower than its minimum ignition temperature or ignition temperature.
Because LED is a solid-state cold light source, it has the advantages of high electro-optical conversion efficiency, low heat generation, low power consumption, safe and low operating voltage, and long service life. Therefore, high-power white light LEDs are explosion-proof lamps, especially portable explosion-proof lamps. A very ideal electric light source for lamps.
LED explosion-proof lamp is a kind of electrical equipment used in special industries, mainly to solve lighting problems. , which is characterized by:
The light-emitting body is a high-power LED module, and a wide-voltage input driving circuit is arranged between the light-emitting body and the battery; the wide-voltage input driving circuit includes a constant current chip, the constant current chip and the battery form a power module, and the LED module is connected to the constant current. On the flow chip, the power module and the LED module are glued together; the lampshade and the lamp housing are ultrasonically welded.
It uses the characteristics of low heat generation of LED to achieve intrinsically safe explosion-proof, and the LED light source has a long life; the LED maintains a constant brightness at the end of full charge and discharge; a heat dissipation device is installed on the lamp housing to achieve effective heat dissipation of the LED module. , to ensure the stability of use, suitable for lighting in coal mines, petroleum, railways, flood control and other industries.
